Ornithogalum plant named ‘BCOR-12.001’

ABSTRACT

A new and distinct cultivar of  Ornithogalum thyrsoides  Jasq. named ‘BCOR-12.001’ originated as a controlled cross between the commercial cultivar  Ornithogalum thyrsoides  Jasq. ‘Beth’ and a variety known as  Ornithogalum thyrsoides  Jasq. ‘10.1’. The cultivar ‘BCOR-12.001’ has R.H.S. 155 D (white group) tepals at maturity and is distinguished from other similar cultivars of which the inventor is aware by its short racemes, wide leaves and suitability for growth in pots.

Botanical classification: Ornithogalum thyrsoides Jasq. ‘BCOR-12.001’.

Variety denomination: ‘BCOR-12.001’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct cultivar of the Lilaceaefamily. The botanical name of the plant is Ornithogalum thyrsoides Jasq.‘BCOR-12.001’.

The new cultivar originated as a seedling from a controlled crossbetween a variety known to the inventor as Ornithogalum thyrsoides‘10.1’ and a variety known as Ornithogalum thyrsoides ‘Beth’. ‘10.1’ wasthe seed parent. ‘10.1’ is the progeny of the commercial variety ‘BockBay’.

The new variety was first noticed, because of its erect and shortracemes.

The new cultivar ‘BCOR-12.001’ has been asexually reproduced undercontrolled environmental conditions at a nursery in Half Moon Bay,Calif. under the direction of the inventor with its distinguishingcharacteristics remaining stable.

‘BCOR-12.001’ is distinguished from other Ornithogalum thyrsoidesvarieties of which the inventor is aware by its short, upright racemesand its suitability for growth in pots.

Asexual reproduction was first accomplished when vegetative cuttingswere taken from the initially selected plant. Examination of asexuallyreproduced, successive generations grown in a nursery at Half Moon Bay,Calif. show that the combination of characteristics as herein disclosedfor ‘BCOR-12.001’ remains firmly fixed.

DESCRIPTION OF THE NEW PLANT

The plants shown in the figures were grown in 3″ pots and were ready forcommercial sale. Plants were grown from bulbs. Three bulbs were placedin each pot. Bulbs are tunicate and R.H.S. 155D (white group).

‘BCOR-12.001’ has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity and day length. Colordeterminations were made with The Royal Horticultural Society (R.H.S.)Colour Chart.

A typical plant with a            mature inflorescence that is ready for sale is approximately            21 cm high when grown in a 3″ pot with appropriate soil            amendments.        -   Growth.—Upright rachis with spreading leaves. Inflorescence            is large and showy. Bulbs are tunicate.        -   Rachis.—The rachis is upright and glaucescent. Its color is            R.H.S. 147 B (yellow-green group). Diameter — 7 mm at base            and 5 mm at top. Length to first floret and bract pair            variable 5-7 cm.        -   Foliage.—Leaves alternate at base of stem, growing alongside            rachis. Shape of leaf. — Fleshy, varying from channeled to            flat, lanceolate. Margins are entire. Apex acute. Texture. —            Glaucescent. Color. — Mature leaves are R.H.S. 147B            (yellow-green group) on both sides. Large leaves are 9 cm            long and 2.5 cm wide (at widest).-   Inflorescence:    -   -   Form.—Corymbose racemes. Indeterminate. Approximately 25 to            30 individual flowers (florets) per inflorescence on            pedicels that elongate as the florets opens, and on average            are as long as 20 mm for mature florets. Flowers do not            produce a fragrance. Young flowers are predominantly white —            R.H.S. 155D (yellow-white group), 15 mm tall and have a            diameter of 7 mm. The rachis for the inflorescence is strong            and upright. The pedicels are predominately green — R.H.S.            144 B (yellow-green group) at maturity and glabrous.

Florets are perfect and complete. Perianth is not keeled.            Perianth can be highly reflexed. Each floret is associated            with a bract that continually elongates and can be as long            as 16 mm when flower is at its prime and is same color as            pedicel — R.H.S. 144 B (yellow-green group). The bracts are            lanceolate with narrowly acute apexes and are approximately            10 mm wide at their base.
